Description

GtkBoolFilter is a simple filter that takes a boolean GtkExpression to determine whether to include items.

Functions

gtk_bool_filter_new ()

GtkBoolFilter *
gtk_bool_filter_new (GtkExpression *expression);

Creates a new bool filter.

Parameters

expression

The expression to evaluate or NULL for none.

 [transfer full][nullable]

Returns

a new GtkBoolFilter

gtk_bool_filter_get_expression ()

GtkExpression *
gtk_bool_filter_get_expression (GtkBoolFilter *self);

Gets the expression that the filter uses to evaluate if an item should be filtered.

Parameters

self

a GtkBoolFilter

Returns

a GtkExpression.

[transfer none]

gtk_bool_filter_set_expression ()

void
gtk_bool_filter_set_expression (GtkBoolFilter *self,
                                GtkExpression *expression);

Sets the expression that the filter uses to check if items should be filtered. The expression must have a value type of G_TYPE_BOOLEAN.

Parameters

self

a GtkBoolFilter

expression

a GtkExpression

gtk_bool_filter_get_invert ()

gboolean
gtk_bool_filter_get_invert (GtkBoolFilter *self);

Returns whether the filter inverts the expression.

Parameters

self

a GtkBoolFilter

Returns

TRUE if the filter inverts

gtk_bool_filter_set_invert ()

void
gtk_bool_filter_set_invert (GtkBoolFilter *self,
                            gboolean invert);

Sets whether the filter should invert the expression.

Parameters

self

a GtkBoolFilter

invert

TRUE to invert

Types and Values

GtkBoolFilter

typedef struct _GtkBoolFilter GtkBoolFilter;
